The Violet ink BL107 Energel-X Retractable Roller Ball Gel pen is for everyday use. It incorporates a generous smooth rubber grip for added comfort and an attractive plastic barrel in the matching colour to the ink inside. It is a 0.7mm tip which gives approximately a 0.35mm line width when writing. It is a low viscosity liquid gel ink allowing a smooth flowing and quicker drying ink than normal gel ink. Because the ink dries quickly it is especially suitable for left handed writers. This is a perfect pen for Office, School or home.
